Abstract
A method for identifying a deviation in a thermal energy circuit is presented. The method comprising: receiving (302) a first hot fluid flow measurement (f1) from a first hot fluid flow sensor (208) arranged in a hot fluid conduit (102); receiving (304) a first cold fluid flow measurement (r1) from a first cold fluid flow sensor (204) arranged in a cold fluid conduit (104); receiving (306) a second hot fluid flow measurement (f2) from a second hot fluid flow sensor (210) arranged in the hot fluid conduit (102) upstream the first hot fluid flow meter (208); receiving (308) a second cold fluid flow measurement (r2) from a second cold fluid flow sensor (206) arranged in the cold fluid conduit (104) downstream the first cold fluid flow sensor (204); receiving (310) a thermal device flow measurement (g) from a thermal device flow sensor (202) configured to measure a thermal device flow of a thermal device (106a) connected to the hot fluid conduit (102) downstream the first hot fluid flow sensor (208) and upstream the second hot fluid flow sensor (210), and to the cold fluid conduit (104) upstream the first cold fluid flow sensor (204) and downstream the second cold fluid flow sensor (206). The method further comprising upon (312) the first hot fluid flow measurement (f1) is different from the second hot fluid flow measurement (f2) and the thermal device flow measurement (g) in combination, generating (314) a first deviation signal indicating a deviation in the hot fluid conduit (102), or upon (316) the first cold fluid flow measurement (r1) is different from the second cold fluid flow measurement (r2) and the thermal device flow measurement (g) in combination, generating (318) a second deviation signal indicating a deviation in the cold fluid conduit (104).
